But alas, the event was not the couple’s walk down the aisle.

Those wedding rumors perked up again when no-parking signs were put up around the house over the weekend and a large shipment of Champagne was delivered Friday. Aniston alsoinvited her hairstylist Chris McMillan to her house to style her coif. The timing was also perfect, since the day marked the one-year anniversary of Theroux’s proposal to the actress. He proposed on his birthday last year , so the rumor mill had that occasion-eclipsing precedent to go on. Maybe this was her way of saying, “Hey, thanks for proposing to me on your big day last year, allow me to return the favor.” The casual affair mostly took place on Aniston’s massive patio and manicured grounds around her pool, Radar Online reported . Theroux and many of the guests reportedly wore jeans.

Partygoers included Ellen DeGeneres and wife Portia de Rossi , Kristen Bell and fiance Dax Shepherd, Tobey Maguire, Isla Fisher and husband Sacha Baron Cohen , Don Cheadle, Jimmy Kimmel, Tobey Maguire and his wife, Jen, Ben Stiller , Jason Bateman and Lake Bell, according to a few reports. Other guests surrounded a fire pit inside the living room, near a huge bar, and an indoor-outdoor deck was home to a buffet of finger foods and small appetizers prepared by Aniston’s personal chefs, E! reported. The affair wrapped up around 11 p.m.

Kaley Cuoco was seen last week in Heidi Klum’s “Project Runway.” She came with another guest judge, Anne Fulenwider of Marie Claire. Aside from Klum, ‘Runway’ regulars are Nina Garcia and Zac Posen. Thanks to its consistently high ratings, “The Big Bang Theory” is making Kaley Cuoco’s name even bigger. It would not be surprising to see Kaley take on rom-com roles in the movies. Jennifer Aniston has had a few film hits, and Kaley may be on the same trail. In TBBT Season 7, Kaley’s Penny will be bonding with Jim Parsons’ Sheldon Cooper. They both miss Leonard (Johnny Galecki) so much, so fans will be treated to their ways of coping with Leonard’s absence.
